Bespoke Sauna Installation in Hampstead & North London
We design and build bespoke saunas for homes across Hampstead and North London, from Hampstead and Islington to Queens Park. Every sauna is measured and built on site to fit the space you have, and fully installed prices start from £9,995, depending on size and design.
North London houses often have generous rooms, basements and gardens, which gives a lot of choice. Many of our projects here replace something that is no longer used: a tired bathroom, a corner of a basement or a garden shed.
Saunas we’ve built in North London
Bathroom replaced with a sauna, Hampstead
A large, tired bathroom became an open, glass-fronted sauna. We built an insulated timber frame with a vapour barrier and lined every surface in Thermo Aspen. A lower and an upper bench allow sitting or lying down, and a frameless glass door and fixed panel bring in daylight from the adjoining bathroom. Discreet LED lighting completes it.
Basement bathroom sauna, Islington
The original brief was a compact two-seater sauna in a basement bathroom; we fitted a full-size sauna into the same space without moving much of the bathroom. The single-phase Harvia Cilindro 9kW heater sits inside an L-shaped lower bench, with a floating upper bench above, concealed LED strips and an 8mm clear glass door.
We have also built a compact garden shed sauna in Queens Park, installed quickly with minimal disruption.
What to plan for in a North London home
-
Basements and lower ground floors. These are a common place for a sauna. We design the ventilation around the room so the sauna heats evenly, and check the access route for timber and the route for power.
-
Converting a bathroom. A bathroom often already has drainage and a good electrical supply nearby, which can make a conversion simpler. We will tell you what needs moving before you commit.
-
Listed buildings and conservation areas. Parts of Hampstead and Highgate are conservation areas, and some houses are listed. Internal work in a listed building may need listed building consent, and a new garden structure may need planning permission. We will flag this early so you can check with the council.
-
Power. The Islington sauna runs on a single-phase heater. We size the heater to the room and tell you what the electrical supply needs before you commit.

Frequently asked questions
How much does a sauna cost in North London?
Our bespoke saunas start from £9,995 fully installed. The final price depends on size, sauna type, timber and how much building work the space needs. Prices are the same across London and Surrey.
Can a bathroom be turned into a sauna?
Yes. In Hampstead we replaced a large bathroom with a glass-fronted sauna, and in Islington we fitted a full-size sauna into a basement bathroom without moving much of the existing furniture.
Can you build a sauna in a basement?
Yes. Basements are one of the most common places we build saunas. We plan the insulation, vapour barrier and ventilation around the room before choosing the heater.
Can a garden shed be turned into a sauna?
Often, yes. In Queens Park we fitted a compact sauna inside a garden shed with minimal disruption. We check the structure, insulation and power supply first.
How long does installation take?
A traditional or infrared sauna typically takes 3–5 days on site. Hybrid and Himalayan salt saunas take 2–3 weeks. We confirm timings in your quotation.
